🔐 What’s 2FA and Why Is It Essential for Crypto Accounts?

[cryptohog]

2FA stands for Two-Factor Authentication — a security layer that requires two separate proofs of identity before you can log in or confirm actions on your account.
How It Works

First factor: Your password.

Second factor: A one-time code generated by an authenticator app (Google Authenticator, Authy) or sent via SMS/email.

Even if someone steals your password, they can’t access your account without the second factor.
Why It’s Critical in Crypto

High-value target: Crypto accounts are directly linked to assets that can be transferred instantly and irreversibly.

Common attack vector: Hackers often obtain passwords through phishing, leaks, or malware.

2FA adds a barrier: Stops 99%+ of automated account takeover attempts.

Best Practices for 2FA in Crypto

Avoid SMS-based 2FA — SIM-swaps can bypass it.

Use an authenticator app or hardware security key (YubiKey).

Backup your 2FA codes securely (offline or on paper).

Bottom Line:
In crypto, losing your account means losing your funds — no “forgot password” can bring them back. 2FA makes your account significantly harder to compromise, which is why every serious trader or investor should have it enabled.
